Don’t worry – there’s a way around the blackout if you know exactly what you’re looking for, thanks to the magic of Google’s all-encompassing cache.
First, boot up your browser and head over to Google, where you’ll just so happen to see a link to a page outlining Google’s own SOPA/PIPA opposition. Search for whatever blacked-out page you’re looking for, but be specific: you won’t be able to browse blacked-out sites normally, so you’ll need to find deeper links to exact content, using searches like “Reddit why is morrowind so revered” or “Maximum PC Wikipedia”.
Trying to click on the link will lead you to the site’s blackout message. Instead, hover over the listing, then mouse over the three arrows that appear to its right to bring up the preview pane. Underneath the direct link in the preview pane, you’ll see a URL for the page, and to the right of that, you’ll see a link to a cached version. Bingo! Click on that.
You’ll be taken to a cached version of the page. A message at the top will tell you when Google took the snapshot. This method isn’t perfect, however; you won’t be able to click on links without being directed to the blackout page. (You can run another specific Google search for the linked-to content, though.) Additionally, the content might not be totally up-to-date, but content that’s a few day old beats no content whatsoever, right?
